PETER E. HUMMEL, OF PULASKI, NEW YORK.

MACHINE FOR SCOURING AND SETTING LEATHER.

Specification forming part of Letters Patent No. 17,576, dated June 16, 1857; Ressued March 19, 1867, No. 2,518.

To all whom t may concern.'

Be it known that I, PETER E. HUMMEL, of Pulaski, in the county of Oswego and State of New York, have invented a new and useful Machine for Scouring and Setting Leather; and I do hereby declare that` the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this speciiication, in which- Figure l, is a side view of my improve ment. Fig. 2, is a transverse section of the reciprocating head and guide bars; w, a', Fig. l, indicates the plane of section.

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists in the employment or use of a reciprocating head provided with tool stocks and used in connection with a rotating table, the parts being arranged as will be hereinafter fully shown and described whereby the process of scouring and setting or extending leather, hitherto performed by hand, may be accomplished in an expeditious and perfect manner.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents a rectangular frame in the upper part of which four pendent rods a) are secured. To the lower ends of these rods guides bars (Z2) are attached, the two guides being parallel with each other and having a plate B fitted between them, the sides of said plate being provided each with a groove in which the guide bars are iitted.

To the under side of the plate B and at each side a pendent frame (c) is secured, and the ends of two shafts (al) (d) are fitted in their frames (c), the ends of the shafts (al) being fitted in bearings (e) which are placed in vertical slots (f) in the frames, and have spiral springs (g) bearing on their upper edges, said springs being placed around vertical guide rods or pins (It) attached to the bearings. The upper ends of the springs (g) have plates placed upon them, 'and screws (jl which pass through the plate B rest or bear upon said plates the springs (g) being more or less compressed and their pressure upon the bearings (e) graduated as desired by turning the screws The shafts (d) (d) are allowed to turn freely in their bearings and a socket (la) is attached to each shaft (d). These sockets (7c) extend the whole length of the shafts and the tools (Z) are fitted within them. These tools are constructed of the usual material, stone or metal, and of the usual flat rectangular form, the corners beingl rounded to prevent injury to the leather.

The shafts (CZ) (d) have each a rod (m) projecting radially from them. These rods (m) have screw threads cut on them, and weights (n.) are fitted thereon, said weights by being turned may be brought nearer to or farther from the shafts (d) (d), so that the tools may be counterpoised and their weight or pressure graduated as may be desired. The shafts (cl), are also allowed to yield or give in consequence of being fitted in the yielding or sliding bearings (e).

A reciprocating motion is given the plate B by means of a connecting rod C and crank D attached to a driving shaft E.

F is a vertical arbor or shaft which is permanently secured to the center of the base G of the frame A. On this arbor or shaft a revolving table or bed H is placed, the upper end of the arbor or shaft fitting in a socket (f) which is secured to the under side of the bed. A collar (g) which is secured to rods (L), attached to the under side of the bed, iits on thearbor or shaft- F. The bed is allowed to turn freely on the arbor or shaft F, and the leather I to be operated upon is stretched out upon the bed H. A reciprocating motion is then given the plate B and consequently the tools (l), by turning the driving shaft E, and the leather isvpresented to the action of the tools so that all parts will be properly acted upon by turning the bed H.

By means of this machine leather may be scoured and set or extended much more expeditiously than by the hand process. The tools are allowed to yield or give and their pressure may be graduated with the greatest facility, and the work performed in a perfect manner.

Having thus described my invention,

what I claim as new, and desire to Secure ets (la), and adjustable counterpoises (a),

by Letters Patent, is: substantially as herein shown and described,
